Scanning Tips
OCR results will be poor if an image is not scanned properly. Remember
the following tips when you scan:
• Scan documents at 300dpi.
• Take the color and quality of your document into account when
scanning.
High-quality documents return better recognition results than
low-quality documents. Shaded, colored, or low-quality
documents may result in poor recognition accuracy unless
adjustments are made before scanning. See “What is the quality
of the original document?” on page 55 for more information.
• Always try to scan an original document instead of a photocopy.
• If you are going to use FAX copies to OCR, ask your FAX sender
to send them to you using their machine’s Best or Fine mode.
• Make sure the page is properly aligned in the scanner.
Select
Automatically straighten page image
in the
Accuracy
settings
of the Options dialog box to automatically straighten a page
image by up to 10 degrees if necessary.
• Check the glass, mirrors, and lenses on your scanner for dust,
smudges, or scratches. Clean if necessary.
• Make sure the proper settings are selected in the
Scanner
tab of
the Options dialog box before scanning.
See “Scanner Settings” on page 46 for more information.
